FT-817ND - My First Modification

Now it is time for my first modification (yeah, right!) - my fat fingers and thumbs do not fit the knobs very well. That is OK, I knew that was going to be a problem before ordering.

I like the idea and feel of VFO Tuning and Menu Selection with my right hand thumb, but the little depression on the tuning knob is; far too small, and too close to the axis of the knob, to provide the leverage necessary to be effective.

A Google search provided links to the "Kranker Knob" and other accessories - but, I did not want the additional expense and did not (really) want to modify my new FT-817.

What is needed; is a crank (nib) for the original stock knob.

The solution was found in the sewing kit. A hat pin, cut to about 3/8 inch, was carefully pushed between the original plastic knob-center and the outer rubber knob band - a tight fit keeps it in place.

The results: the "Knib Knob" (c) was invented.

And, They Come in Designer Colours

Note: only the red pin has been cut to the required length

The modification looks and feels very natural. With your right thumb-pad resting on the Knib Knob, it is easy to spin the knob, pick a menu item, or do fine tuning of the VFO, with very little effort.

The Knib Knob is a QRP size modification for a QRP size Rig.

Note: Thinking about it, a "U" shaped bent pin may provide even more Knib Knob stability - something I may try. Also, a more permanent installation could include a small hole in the edge of the knob to press fit the pin.
